Specification of Letters Patent.

Application led March `17, 1914. Serial No. 825,249.1A

To' 'all'whom itmay concern:

Bei-it known that iI," EDWARD Nl Moon, a citizen of the `United States,residing at @alsv landfinthecountyof Alameda and Stateoty California,have `invented :certain new and useful mprovements in1 Traverse-Machinesfor Lathes,of which the `followinglis a speci- Imation;-

My invention relates to the general class of llathe attachments and'particularly to traverse-machinesadapted for suchwork as gear'-`cutting, milling," indexing, drilling, grinding, etc. My invention'isparticularlyV adapted for and is applicable to that generaltypev ofthesetraverse:attachments of *.vhich the-machinepatented by me September23, 1913,' No.- 1,073,698,A is -an illustration, and my invention, in asense, maybe consideredas anf'improvement on said machine, the generalobject of' the improvement` being to adapt-'saidmachine for a. varietyof condi? tions and uses thereby making it more' elli cient.

To this end Emy invention consists in the'- novel machine and in theconstructiomoar-4 rangement and vcombination of its parts which I shallnow fullydescribeby reference toJ the accompanying drawings, in which'-Figure 1 is a yfront elevation of -my machine. Fig. 2 is an end View ofthe same. Fig. 3 is an elevation showing' the worm gearing.` Fig.4 is anelevation of my ina-- chine showing the spindle and its connec tionsturned to a position parallel with the stock. Fig. 5 is a longitudinalsection of the spindle carrier. Fig. 6 is an elevation of my machineshowing the use ofa stepped pulley for variable speed driving. F ig. 7is an end elevation of Fig. 6. Fig. S is a fragmentary view showing thespindle pulley. Fig.v` 9 is an elevation of my machine showing thev useof an index plate and index pin. Fig. 10 is an elevation, partly insection, of the same, taken at right angles to the elevation of Fig. 9.

1 is a rigid column which forms the stock of the machine. This columnhas passed through it longitudinally a bolt 2, the lower end of whichhas a foot flange 3 and its upper end a nut 4, bearing upon a cap 5 onthe column head. By means of the footflange 3 the stock 1 is fitted tothe lathe toolpost support in the usual manner and is clamped thereto bythe bolt 2 and nut 4.

About the column-stock 1, on a spline or feather7 thereon, ist'ted thesplit sleeve S adapted for'i lineal adjustment on the stock, and tobe'rigidly'fiied by means of screwbei'ng seated in a Ylug '13 projectingfrom` the cap 5.' The screw is threaded` througha nut-15 of the sleeve8.

The sleeve r8 is formediwith a circular bearing face 16 having 'acentral boss 17, andan annular "l'shaped slot-18. To--the circularbearing vface/1G is fitted the flangebody 190i thefsp'indle carrier'20.'The fitting -is onel which will'permit thevangular adjustment of thespindle carrier relatively tolthefbearing face 16 of the'sleeve 8, apivotal connection'being made lby fitting the flange-body 19 rotatablyupon thelcentral boss'17 of the bearing'fa'ce 1G. The connection isinsured by a central bolt 21, and is rendered rigid in the variousangular adjustments, bythe three bolts 22 which have their heads fittedin the annular slot-18 of said bearing 'facef16- Thecentral bolt 21 andtwo of thefbolts 22, flanking 'the-cen# tral boltyfrm a line of boltswhich are `made to serve the double 'purpose of'holdingl thel bearing4face 16 and the flange body 19 together, and ot serving to clampthesplit spindlecarrier together at its meeting edges, as shown clearly inFig. Ll.

23 is an arm which by means of a `split foot-clamp 23" is rotatablyfitted upon the spindle housing 24 which is clamped-in the spindlecarrier'20. The arm is Xed in any angular position to which it may beadjusted, by means ot'a bolt 25 in its footclamp.- The'arm'23isslottedat 26in'a radial line having the spindle carrier for a center.Thisarm A3 serves as a holder for adjustably attaching various devicesto be used in the many operations and positions of which the machine iscapable. Thus in Figs. 1, 2 and 3, I show this arm in connection with aspindle driving mechanism, adapted to be operated by an overheadcountershaft.

27 is a plate which carries a short shaft 28, with a pulley 29 toreceive the power. The shaft 28 has a worm 30. The plate 27 is carriedby the arm 23, being clamped thereto and adjustable in the slot 26thereof by the back plate 31 and the bolts 32 which pass through and areadapted to move in said slot. The worm 30 engages with a Patented Oct.6, 1914.-

worm gear 33 on the spindle 34 of the machine. rlhe adjustment of theshaft 28 provides for varied distances from the spindle axis and,therefore, for Various diameters of gears Whether of the Worm or spurtype. Also the angular adjustment of the arm 23 about the spindlehousing serves as a belt tightener for the overhead belt.

As l have shown in Fig. 4, the spindlecarrier together With all itsconnections may itselil be adjusted to various positions, as, forexample, parallel With the stock, by turning its body flange relativelyto the bearing face of the sleeve 8.

In Figs. 6, 7 and 8, I shoW the slotted arm 23 as having applied to it abelt and pulley transmission of the stepped-pulley type, for'variablespeed. In this case a stepped pulley 35 is carried on a short shaft 36,adapted to be adjusted in the` slotted arm and fixed thereto by a nut37. 38 is the belt from an overhead countershaft to a pulley 39 on theshaft 36. 39 is a belt from the stepped-pulley to a pulley 40 on thespindle 34.

ln Figs. 9 and 10, I show the use of the slotted arm 23 in connectionWith an index pin 41 adjustably carried therein, as seen in Fig. l0, andan index plate 42 carried on the spindle 34.

rShe spindle housing 24 Which is clamped in the spindle carrier 20 isshown in Fig. 5 as containing the spindle 34, with its pulley 40, thebushings 43, the chuck 44, and the draw-in rod45 with its handle 46.

ln the several figures, the tool of the spindle is shown with abrasiveWheels 47. though it is to be understood that other tools may besubstituted, according to the Work, such, for example, as circularmilling cutters, fly-cutters, drills and drill-chucks, etc.

I claim l. A traverse machine for lathes comprising a stock with meansfor securing it to the lathe member; a member fitted to said stock forlineal adjustment thereon; a spindlecarrier carried by said member andangularly adjustable With relation thereto; a

spindle-housing 'clamped in the carrier', and having a tool-operatingspindle therein; an arm carried by and radially extending from thespindle housing, said arm being angularly adjustable on said housing;devices adjustably carried by said radial arm; and devices carried bythe spindle and coacting with the devices carried by the radial arm.

2. A traverse machine for lathes comprising a stock With means forsecuring it to the lathe member; a member itted to said stock for linealadjustment thereon; a spindle-carrier carried by said member andangularly adjustable with relation thereto; a spindle-housing clamped inthe carrier, and having a tool-operating spindle therein; an arm carriedby and radially extending from the spindle housing, said arm having anelongated lineal slot and being pivotally mounted for angular adjustmenton said housing; devices carried by'said arm and adjustable in thelineal slot thereof; and devices carried the spindle and coacting Withthe devices carried by the radial arm.

3. A traverse machine for lathes comprising a stock With means forsecuring it to the lathe member; a member fitted to said stock forlineal adjustment thereon, said member having a circular bearing face; asplit-car` rier for the spindle, having a flange-body, a central boltpassing through the meeting edges of the split spindle carrier to clampsaid carrier, said bolt also passing through the flange-body of thespindle carrier into the bearing face of the lineally adjustable memberto pivotally connect said parts; and lateral bolts also clampingv thespindle carrier and passing through the flange body into the bearing:tace and having a circular play in said face. l

In testimony whereof l have signed my name to this specication in thepresence of tWo subscribing Witnesses.
